Hi David, Solved, Finally, I checked out a new GIT tree, the previous I used is linux-2.6.23-rc3-omap1(might be quite old). As you said, I modified the board-(MYBOARD).c file. Also, The NAND flash part is the Samsung K5E1212ACB MCP(64MB NAND flash/64MB DDR), as the IDs shown below, NAND device: Manufacturer ID: 0xec, Chip ID: 0x36 (Samsung NAND 64MiB 1,8V 8-bit ) Scanning device for bad blocks Bad eraseblock 753 at 0x00bc4000 Bad eraseblock 1007 at 0x00fbc000 Bad eraseblock 1112 at 0x01160000 Bad eraseblock 1281 at 0x01404000 Bad eraseblock 1948 at 0x01e70000 Bad eraseblock 2158 at 0x021b8000 Bad eraseblock 2328 at 0x02460000 Bad eraseblock 2941 at 0x02df4000 Creating 5 MTD partitions on "omapnand.0": 0x00000000-0x00010000 : "xloader" mtd: Giving out device 0 to xloader 0x00010000-0x00050000 : "bootloader" mtd: Giving out device 1 to bootloader 0x00050000-0x00080000 : "params" mtd: Giving out device 2 to params 0x00080000-0x00280000 : "kernel" mtd: Giving out device 3 to kernel 0x00280000-0x04000000 : "filesystem" mtd: Giving out device 4 to filesystem On Thu, Mar 13, 2008 at 12:19 PM, David Brownell <david-b@xxxxxxxxxxx> wrote: > On Wednesday 12 March 2008, you wrote: > > I added the MTD partition information to board-($MYBOARD).c, > > But kernel didn't show any MTD partition information during booting. > > That means you didn't connect something correctly.
